JAMES P. HYDE, on NEW YORK, N. Y.

i vAPPARATUS FOR FLUSHING WATER-CLOSE'II'S AND URINALS.

SPECIFICATION forming part of Letters Patent No. 259,985, dated June 20,1882.l

` Application tiled May 20, 1882. (No model.)

To all whom it may concern Be it known that I, JAMES P. HYDE, acitii zenof the United States, residing at New York,

in the county of New York and State'of New York,'have invented new anduseful Improvementsin Apparatus for Flushing Water-Glosets and Urinals,of which the following is a specification.

This invention relates to that class of apparatus in-which a siphon isemployed for the purpose lof flushing water-closets, urinals, and thelike.

The main object of my invention is to provide a cistern or supply-tankand an independent service-box or dashing-tank, with the la t ter sodisposed with relation to the former that the water in the cisterncannot rise above the overow-level in the ilushing-tank. A furtherobject is cheapness and simplicity of construction, compactness, andadaptability to be readily put up wherever designed. These objects Iattain by means of the devices illustrated in the drawings, in which-Figure 1 represents a section taken through my improved apparatus Fig.2, a like view of a modied form.

The cistern A and the service-box or ilushing-tank B, both ofappropriate shape and capacity, communicate with each other by suitablepipe-connection, O.

The tlow of water from the cistern into the service-box or flushing-tankis regulated by a cock, D, which can be turned so as to regulate thesize of stream passing from the former to the latter, according to theperiod of time which it is desired shall elapse before it shall attainsuch level in the linshing-tank as will admit of it being siphoned offfrom the same.

Within the flushing-tank is an ordinary siphon, E, from which the pipecan be conducted to either a water-closet or a nrinal, as preferred, thebend in said siphon being below the top of the ushing-tank.

The sphon is inclosed by a bell, F, closed at its top and open at itsbottom, the said bell inclosing the bend and both legs of the siphon,

n and being connected by a link or rod with the lifting-lever G, whichis operated by a cord or 2O if so :YU

""chain, H, when it becomes desirable to` raise the bell so as to fillthe siphon.` Y 'When the flushing-tank is filled with water to a levelabove the bend in the siphon the said bend will extend above thewater-level in the bell into the body of compressed air contained in theupper portion ofthe latter, the weight of the bell serving to keep itseated upon suitablelegs, f, located at the bottomof the tank. If nowthe chain or cord, which extends to within convenient reach of theperson using the closet or urinal, be pulled, the lever will raise thebell, so that the water therein, which is normally below the bend, and alower level than at the water-level in the flushing-tank, will riseabove the bend in the siphon, thereby causing the latter to ll and drawoff the contents of the tank, so as to flush the closet or urinal. Assoon as emptied the tank commences to refill, the water being suppliedthereto from the cistern in a small graduated stream. In order now toautomatically check the iniiow of water from the cistern into theflushing-tank before it reaches the overflowlevel in the latter, Iprovide in the cistern a float-valve, H, adapted to control the feed ofyWater into the cistern, the said valve being set so that as soon as thewater in the cistern has attained a level just below the overflow-levelvin the ilushing-tank the oat-valve will cut off the feed of waterintothe cistern. This level being determined, it will be obvious that itwill be at all times substantially maintained in the cistern, since thewater passes slowly therefrom into the flushing-tank, and the valveopens as soon as the float commences to drop.

Fig. 2 is the same in principle as Fig. 1, the flushing-tank in thisinstance Vbeing located within the cistern, and the siphon formed by atube or cylinder, I, closed at its top and placed over the straight pipeK. In this iigure the valve or cock is preferably located within theushing-tank, the water passing directly through its short pipe from thecistern to the flushing-tank.

From the foregoing it will be seen that the lushin g-tank is placed atsuch elevation with relation to the cistern or supply-tank that thewater-level in thelatter shall not come above the overilow-level in theservice-box or flushi ing-tank.

C indicates branch pipes, which can be arranged to lead oif to smallerdashing-tanks in other localities, as may be desired.

IOO

What I claim is- 1. In an apparatus for flushing Waterclosets andurinals, the combination, with a siphon located Within theflushing-tank, of a bell inclosing the two legs of the siphon andprovided with an open bottom and a closed top, and devices for raisingthe bell, whereby as the bell is lifted the 'atmospheric pressure uponthe water in the tank around the bell will cause the watenwithin thelatter to rise above the bend in the siphon, substantially as described.

2. The combination, with the supply-cistern having a float-valve, oftheflushing-tank counected with the cistern, the siphon located Within theflushing-tank, a bell having an open bottom and inclosing the two legsof the siphon, and devices for raising the bell, whereby the water-levelin the Bushing-tank shall normally be above the Water-level in the bell,

in which latter the water-level is normally be- 2o In teslimony whereofI have hereunto set my 25 hand in thepresence of two subscribingWitnesses.

JAMES P. HYDE.
